Looking at buying a 1983 Pentax 85ED / 1000mm [F.11.8] in excellent condition from my local optics dealer. Comes with box, EQ mount, motor drive, filters and set of Pentax .96in.EP's. [I think it's a claasic ?].
Cost would be around $US2300 which is around the price of a Televue 76 APO here in New Zealand.
There is very little info on these apparently rare Pentax ED scopes.
No reviews, no real information on the web. – nothing.
I know the optics and build qualities are high quality and they were expensive. Pentax stopped making astro. telescopes in 2008.
I do have a Pentax brochure from the mid 1980s with Halley's comet predominant on the cover. They had a 100mm, 85mm, 75mm, 65mm ED / achro versions along with the J80 and J60 series. The ED's had the SMC coatings and the .96 Eps.
Unsure what ED glass they had back then. It does in the brochure it states
'extra low dispersion characteristics surpassing Flourite'.
Expensive, but I feel this is a good buy but I am an emotional buyer so more sensible comments would be appreciated.
[I have not been able to use the scope as yet].
